Remembering where we came from is what steers our future.

Our team is cranking away on a handful of XR2 chassis as we eagerly await the final iteration of our first full carbon fiber sand car bodies.

The talented crew over at FiberwerX has been working closely with us to bring these bodies to life, and we can’t wait to see the finished product come together.

The next generation of XR2 is taking shape.

A monster that never got it’s chance…

This custom Double Throw Down 2 was built to be a custom mid engine configuration with our big Platinum chassis suspension from over a decade ago.

After sitting in hibernation for years, our good friend Mike has decided it’s time to build his dream mid engine and this hybrid chassis would do just the trick. We can’t wait to see this monster finally get its chance to shine.
